SPECIFICATIN frming part of Letters Patent No. 627,391, dated June 2o, 1899.

Application filed March 6, 1893. Serial No. 464,760. (No model.)

To a/ZZ whom, it 71u03/ concern:

Be it known that I, FRANK CHALLONER, of Oshkosh,-in the county of Winnebago and State of Visconsim-have in vented certain new and useful Improvements in Shingle-Sawing Machines; and I do hereby declare that the followin gis la full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to makev subjected to less strain, of a novel spaltingde-` vice, and of a cable carriage-driving device,

together with certain minor improvements in the details of construction and arrangement of other parts of the machine hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several iignres.

Figure l isV a plan view of a machine embodying my improvements, portions of the carriage beiugbroken away or omitted. Fig. 2 is a side elevation of the machine viewed from the right with reference to Fig. 1 and intended to show particularly the carriagedriving mechanism. Fig. 3 is a partial elevation of the spalting device and a partial vertical section on the line 3 3, Fig. l. Fig. 4 is a similar elevation of the spalting device and partial section of the machine on the line 4 4:, Fig. l; and Figs. 5 to i), inclusive, illusv trate certain details of the inachine.

The frame consists of a spider-A, supported on legs a a from a vbase B, or it may be of any other form and construction which will af- C is a rotary carriage mounted upon the upper end ot a Shaft c a short distance above the spider A and formed next to the rim with a circular series of bolt receptacles or openings, each of which is provided at the inner end with a iixed dog c and at the outer end with a movable dog c2. The movable dog of each block-receptacle is carried toward the fixed dog by a spring c3. (Shown at the right hand of Fig. l.)

D D are two horizontal saws arranged on opposite sides of the machine just below the block-receptacles in the carriage, andE E are the tilt-tables, also arranged on opposite sides of the machine adjacent to and just in ad- Vance of the saws in the usual mannerin this class of machines.

f f are dog-opening levers, each f ulcrumed to the carriage C and connected at one end with the outer movable dog c2 of the adjacent 7o block-receptacle. To the opposite end of each of these levers is pivoted an oblong polygonal block. F, the ends of which are adapted to rest against the inside of the carriage-rim and `hold the movable dog c2 open against the ten- 75 sion of spring c3. Each block F is formed or 'provided on the under side with a friction rollerf, (shown in Fig. 3,) which is adapted to engage the inclines]c2 f2, and therebyvto be vmoved inwardly and turned a quarter of a 8o revolution, carrying the movable dog c2 outwardly and turning the block F from the position in which it is shown at the left handin Fig. l to the position in which it is 'shown atl the top of Fig. l,with one end bearing squarely 85. against the rim of the carriage. By this means the dog will be held open without the slightest obstruction to the movement of the carriage until the block F is given a quarterturn, thereby carrying the end out of contact 9o with the carriage rim and permitting the spring c3 to torce said dog inwardly toward the opposite xed dog c. The inclines fzf2 are attached to projecting arms of the spider A on opposite sides of the machineland are made vertically adjustable,as shown in detail, on an enlarged scale, in Figs. 5 and G. Just in advance of these inclines I provide inford the necessary supports and bearings for v'wardly-inclined springs ffs'in the path of the rollers f' to turn the blocks F into the loo the mechanism hereinafter described.

proper position to insure the inclines f2f2 turning them, so as to present their ends squarely to the rim of the carriage, and thus hold the movable dogs open the required distance in the movement of the carriage.

f4f4 are inclines attached to the frame of the machine in the path of rollers f' a short distance in advance of the tilt-tables and in position to turn the blocks F from end to side against the carriage-rim, thereby releasing the movable dogs and permitting the springs by which they are actuated to force them into engagement with the blocks as they rest upon the tilt-tables.

It is obvious that in connection with the dog opening and holding devices hereinbefore described any suitable forms of springs and connections other than those shown may be employed for forcing the movable dogs inwardly.

The carriage is supported and guided at the rim by wearing-blocks A' A', which are held in vertically-adjustable sockets or holders CL2, attached to projecting arms of the spiderframe A by means of brackets a' a'. (Shown in detail in Figs. 5 to 7, inclusive.) These wearing-blocks are made of wood or other suitable tough fibrous material and are formed in their wearing-faces with holes or recesses which are filled with graphite or other lubrieating material. They are adjusted vertically by means of screws c3. Two of the brackets d' a' serve also for the attachment of the inclinesf2 and springsf.

G is a horizontal counter-shaft supported in bracket-bearings projecting from lthe spider-frame A a short distance below and parallel with a tangent to the carriage. It is provided with a cone-pulley g, loosely mounted thereon and arranged to be connected and disconnected therewith by means of a clutch g under the control of the operator, who stands on the opposite side of the machine by the table A2, through the lever g2 and rod g3 or other suitable connections.4 The shaft G is connected bya pinion gtand gear ZL with a shaft located above and at or near the level of the carriage and provided with a grooved pulley II. A cable ZL' passes around the rim of the carriage, which is grooved to receive it, and over pulley I-I, to which it is guided above and below by the sheaves 712752. By this means the desired rotary movement is imparted to the carriage from the countershaft G, the speed of which may be varied by shifting the belt on the cone-pulley g. The usual rack-andpinion feed is dispensed with and an elastic driving connection with the carriage provided, whereby any obstruction to the movement of the carriage, such as the sudden stopping of either of the saws, will arrest the movement of the carriage without injury to its driving connections or other parts of the machine, the cable Zt' slipping on the riln of the carriage or on the driving-pulley H.

Between one of the saws D and the tilt-table E, on the side of the machine adjacent to the table A2, is placed the spalting device, which consists of a stationary leaf or support I and a longitudinally-movable leaf or support I', together constituting an arc-shaped way, concentric with and directly below the openings in the carriage. The leaf I is supported by brackets or standards from the spider A, as shown in Fig. 4, and is provided on the under side with guides which embrace the edges of the movable leaf I', supporting and holding it in the proper position relative thereto, and at the end adjacent to leaf I' with vertical inclines it' on each side thereof, whereby blocks dropped upon the leaf I when it is in normal position are carried upon the leaf I and prevented from catching against the end overlapping said leaf I'.

Referring to Fig. 3, the movable leaf I' is attached to the outer end of a horizontal arm K, which has a collar at its inner end loosely encircling the carriage-shaft c. Ze is a brace located in the same vertical plane with the arm K and pivotally attached at its upper outer end to the outer end of said arm and at its lower end to a collar which loosely encircles the lower end of the carriage-shaft c and rests upon a vertically-adjustable ring Za', by means of which the leaf I' may be accurately adjusted to the required level to work properly with the guides on the lower side of leaf I. A spiral sprin g 752, placed around the carriageshaft c and secured at one end to the collar at the lower end of brace Zo and at the other end to a yoke 7e3, serves to return the lnovable leaf I' of the spalter to its normal position after it has been advanced under the leaf I, as hereinafter explained. Upon the carriageshaft e, a short distance below the spider A, is fixed a disk L, to the under side of which are pivoted, near the rim, a series of T-shaped dogs ZZ, corresponding in number with block receptacles or openings in the carriage. Each dog is provided on the under side, at or near the junction of its stem and cross-piece, with a friction-roller Z' and is pivoted to the disk L at or near the end of its stem opposite the cross-piece. The brace Zt is provided with a projection Z2, in position to be engaged by the outwardly-projecting portion ofthe cross-arm of a dog Z when it is turned into abnormal position for the purpose of carrying the movable leaf I' forward underneath the fixed leaf I, and thereby presenting an opening for the discharge of a spalt from the carriage.

As shown in Figs. l, 2, and 4, M is a horizontal lever projecting from a point below the operators table A2 to a point below and near the rim of disk L and fulcrumed at an intermediate point in its length to a bracket rising from the base B. It is formed at its inner end with a horizontal incline m and a vertical ineline m', as shown in Fig. S, andat its outer end it is pivoted to a vertical rod m2, passing upwardly through a bracket adjacent to the table A2, within convenient reach of the operator. The incline m when the inner end of lever N is raised is in the path of the friction- IOO IIO

'rollers Z', and the incline m is in the path of the inwardly-projecting portions of the crosspieces on dogs Z, as seen in Fig. 1.

N is a hook pivoted to the spider A in position to ride over and catch the arm K, and thereby hold the leaf I in the position in which it is shown in Figs. l and 4, closing the opening through which the spalts are dropped from the carriage. It is connected by a vertical rod nwith a horizontal lever it', extending radially inward to a point adjacent to the periphery of disk L and fulcru med at an intermediate point to a bracket depending from spider A, as shown in Figs. 3 and 4. At its inner end the lever a is formed or provided with a vertical incline n2, which is in the path of the outwardly-projecting portions of the cross-pieces of dogs l l when the latter are thrust outwardly into abnormal position. O is a similar hook beveled to ride under and engage with the arm K when the leaf I is advanced underneath the stationary leaf I and to hold said leaf I in its advanced position until it is released, as hereinafter explained. The hook O is fulcrumed at an intermediate point in its length to a bracket rising from spider A and is connected at the end opposite the hook, by a rod o, with a lever o', fulcrumed at an intermediate point therein to a bracket on spider A and formed or provided on its inner end, below and near the periphery of the disk L, with a vertical incline 02, which when the dogs l lare in normal position is in the path of the inwardly-projecting portions of their cross-arms.

P is a horizontal incline fixed toasuitable support on the frame of the machine, which may conveniently be the bracket to which the lever o' is fulcrumed. It is located in the path of the friction-rollers Z when the dogs I, by which they are carried, are turned outwardly into abnormal position.

Q is a buffer consisting of a cylinder attached to an arm of spider Aand of a piston, which has a stem held normally by a light coiled spring projecting through the front end of the cylinder in the path of a projection on arm K and serving to check the return movement of the leaf I without shock thereto or its connections.

Upon the opposite side of the machine from the spalting -device I provide a permanent arc-shaped supporting-way J, corresponding in position with that of the leaves I and I'.'

My improved machine operates as follows: The saws and carriage being set in motion and driven in the direction indicated by the arrows in Fig. l, blocks are placed in the seyeral receptacles of the carriage as they pass the operators table A2, the movable dog c2 of each receptacle being held outwardly by the adjacent block F and lever f while said block is passing betweenthe inclinesf2 and f4. Be-

tween these points the blocks rest upon the leaves I and I and the tilt-table E on one side of the machine and upon the leaf or support J and the tilt-table E on the other side of the machine. The tilt-tables E E being set normally at opposite inclinations with reference to the center of the machine cause the butts and points to .be `Acut alternately from opposite ends of the several shingle blocks or bolts. While the blocks rest upon the tilttables, the dogs c2 are released by the engagement of rollers f with the inclines f4 and the turning of the blocks F from yend tol side against the carriage-rim and are forced by springs o3 into engagement with the shingleblocks, which are thereby firmly-held in place while they pass the saws and shingles are cut from their under sides. The inclined springs f5 engaging the rollers f' just prior to their engagement with the inclinesf2 insure the blocks F being turned into the proper position with their longer sides against the carriage-rim, so that the inclines]L12 will not fail to turn them into position to present their ends squarely against the carriage-rim. It will be observed that the operation of the dogs, as above explained, oers no resistance to the movement of the carriage except for very short intervals, (while the rollers f engage with the inclinesfz, the springs f3, and the inclines f4,) the movable dogs being held closed in engagement with the shingle-blocks by springs c3 and held open by the blocks F, resting with their ends against the carriagerim during their passage between said inclines. When the leaf I of the spalting device is in its normal position, as shown in Figs. l and 4, the shingle-blocks are dropped thereon by the opening of the movable dogs c2 at that point and are carried by the carriage thereon over the fixed leaf I to and upon the adjacent tilt-table E, the inclines 1l t guiding the blocks over the end of leaf I which overlaps the movable leaf I. The two leaves I and I' thus serve ordinarily as a curved supporting- Way for holding the shingle-blocks in place in the carriage when theyare undogged and guidin g them to and upon the adjacent tilt-table in the same Way that the curved support J performs the same function on the opposite side of the machine. When, however, it is desired to drop the block or spalt from any receptacle in the carriage, the movable leaf I is advanced underneath the iixed leaf I, presenting an opening through which said block or spalt IOO IIO

IIS

falls when it is brought by the carriage over that point and is undogged in the manner hereinbefore explained. To drop a block or spalt from any receptacle in the carriage, the operator depresses the rod m2, when that receptacle passes in front of him adjacent to the table A2, and thereby raises the incline m at the inner end of lever M into the path of the rollers Z' when they are in their inner normal positions. The incline m thus elevated is engaged by the roller Z of the dog l, corresponding with the receptacle from which the block or spalt is to be dropped. This dog is thus moved outwardly and the inner end of its cross-arm as it passes over the incline mf restores lever M and its connections to their normal position, the dog remaining in its outer position. Just before the said receptacle arrives at the spalt-dropper the outer projecting end of the cross-arm of said dog passes over the incline n2and through its connections, hereinbefore described, raises the hook N out of engagement with the arm K, thereby releasing the movable leaf I. The outwardly-projecting arm of said dog thereupon engages the projection Z2 on brace 7c and carries the leaf I forward with the carriage underneath the xed leaf I, thereby presenting an opening through which the shingle block or spalt is dropped as it passes over it. As the leaf I' arrives at the limit of its ad.- vance movement the roller l 011 the dog, by which the leaf is moved, engages with the xed incline Pand is returned thereby to its inner normal position. At the same time the arm K passes over and is automatically engaged by hook O, which holds said leaf I underneath the leaf I. The next succeeding dog, however, engages by the inwardly-projecting end of its cross-arm (if in normal position) with the incline o2, thereby depressing said hook O through its connections, hereinbefore described, and releasing the movable leaf I', which is returned to its normal position by the action of spring k2, its return movement being checked by the buffer Q. Upon arriving at the limit of its return movement the arm K passes under and is automatically engaged by hook N. In this way a shingle block or spalt may be dropped from any receptacle in the carriage by simply depressing the rod m2 at the proper time.

In case it is desired to drop the blocks or spalts from two or more adjoining receptacles in succession .the rod m2 is repeatedly depressed, so as to throw the corresponding dogs Z Z on disk L into their outer positions. The first dog of a series thus moved outwardly operates in the manner hereinbefore explained to first release the movable leaf I and then carry it forwardunderneath the fixed leaf I, where it is automatically held by the hook O. The one or more succeeding dogs being moved outwardly out of range of the incline o2 will not disengage the hook O from arm K, and thus release the leaf I until the blocks or spalts have been dropped from each of the receptacles for which the rod 'm2 has been depressed and the dogs Z l thereby turned outwardly. The inner end of the cross-arm of the first dog in normal position will, however, engage the incline o2 and release said leaf I in the manner above eX- plained.

Various changes in details of construction and arrangement may be made within the spirit of my invention.
